Yes, it sounds really easy in theory, but you never how it will turn out to be in reality:
Swen on Twtter a few days ago: "This job sometimes?Just checked DHL - it seems after it arrived at Heathrow yesterday morning, it was then mistakenly sent to Uganda? "
Stefan - Fancy Exhiled Tormented WOOS today in the Kickstarter comments:"No Dices? Was that the shipment to "Uganda"?"
Swen in the Kickstarter comments:"No, that was the DVD we sent to PEGI to complete the age rating."
This was just to demonstrate what could possibly go wrong in reality
(Btw, I am not saying that your proposed solution is not doable, I am just pointing out that Larian might have some logistic difficulties to pull it through)
